We know that area=0.5*base*height.
Thus, the equation would look like:
127.5=0.5*base*height
That means, 255 = base*height.
We know base is 17
Then, we divide 255 by 17. That gets us the height.
The height equals 15.
Remove parentheses.
-3/8 -1/6
Find the Least Common Denominator (LCD) of 3/8, 1/6. In other words, find the Least Common Multiple (LCM) of 8,6.
LCD=24
Make the denominators the same as the LCD.
- 3x3/8x3 - 1x4/6x4
Simplify. Denominators are now the same
-9/24 - 4/24
Join the denominators
-9-4/24
Simplify
-13/24
Answer:
165
Step-by-step explanation:
Let o and b represent the numbers of orchestra and balcony tickets bought, respectively.
o + b ≥ 250 . . . . at least 250 tickets will be bought
o = b - 80 . . . . . there will be 80 fewer orchestra than balcony bought
Substituting for o, we have ...
(b -80) +b ≥ 250
2b ≥ 330 . . . . . . . add 80
b ≥ 165 . . . . . . . . .divide by 2
The least number of balcony tickets the club could buy is 165.
Answer:
D. 18
Step-by-step explanation:
change 20% to decimal by dividing by 100.
20/100 = 0.20
Now multiply by 90.
90 x 0.20 = 18
